開車前請先開窗

開車的民眾要注意，根據美國加州大學的研究發現，汽車的儀表板、沙發、內裝和芳香劑，會揮發致癌物質「苯」。

苯類化合物是很強的致癌物質，也是很強的骨髓毒性物質，它會造成一般人的貧血或者是白血球稀少，長期暴露的話，得到白血病，就是血癌的風險大為增加，有些孕婦還會因此流產。

和室內每立方公尺苯的正常標準值50微克相比，室溫下的密閉汽車裡含有400到800微克的苯，如果在太陽下曝曬1小時，溫度超過攝氏60度，苯含量更高達2000到4000微克，是正常標準的40倍以上，開車族不能倖免吸入過量的苯。

林口長庚毒物科主任林杰樑：「你的愛車停在太陽底下超過１個鐘頭，甚至不需要１個鐘頭的時候，你要去開車的時候，你要切記，一定要把窗戶搖開把門打開，讓這些有毒氣體揮散掉以後，你才能夠開車。」

醫師指出，「苯」屬於肝腎代謝的有毒化學物質，人體很難自然排出，只能提醒民眾在開車前請先開窗。

Open the windows after you enter your car

According to research done by a U.C., the car dashboard, sofa, air freshener will emit Benzene, a cancer causing toxin (carcinogen) .

In addition to causing cancer, it poisons your bones, causes anemia, and reduces white blood cells.

Prolonged exposure will cause Leukemia, increasing the risk of cancer. May also cause miscarriage. Acceptable Benezene level indoors is 50 mg per sq. ft. A car parked indoors with the windows closed will contain 400-800 mg of Benezene. If parked outdoors under the sun at a temperature above 60 degrees F, the Benezene level goes up to 2000-4000 mg, 40 times the acceptable level. The people inside the car will inevitably inhale an excess amount of the toxin.

It is recommended that you open the windows and door to give time for the interior to air out before you enter.

Benzene is a toxin that affects your kidney and liver, and is difficult for your body to expel.
